Answer:
x=-7/4
Step-by-step explanation:
4x+7=0
4x=-7+0
4x=-7
x=-7/4
An equation typically has a slope. Since there is no equation given, I am assuming that 1/7 is the slope:)
1/7 simplified into decimal form is is 0.1428!
21v + 8 - 12v - 7 + 3t - 1t = (combine like terms)
9v + 2t + 1 <==
In order for two lines to be perpendicular, their slopes must multiply together to equal to negative one
So we do negative one divided by 2/5 to get the slope of the red line
Which is -5/2
To check, we do 2/5 multiplied by -5/2 which equals to -1 so our answer is correct
